Screening of biomarkers in the circRNA signature construction diagnostic model. (A) Mean square error in Lasso regression versus Log (λ); (B) Regression coefficient versus Log (λ); (C) Random forest and xgboost top20 score graph; (D) Venn diagram for machine learning feature selection. The numbers represent the number of genes in each interval, and the percentages come from the proportion of the number of genes to all the genes screened by the three methods
